Abstract
The present invention relates to a thread producing tool for rolling compound thread and its producing method. In particular, it relates to a screw-plate or screw-roller used when the thread-rolling tool is used for rolling thread and its producing method of said screw-plate and screw-roller. It is characterized by that the surface of thread-producing tool for rolling compound thread possesses two kinds of threads with different turning direction, and the crests of said two screw threads are intercrossed, and the method for making this thread-producing tool includes the following steps: firstly, grinding a compound thread roller, then using the compound thread roller to extrude thread-producing tool blank to obtain the thread-producing tool for rolling compound thread.
Description
The present invention relates to a kind of threading tool and processing method thereof of rolling compound thread, the screw plate that uses when especially referring to thread rolling machine or screw-rolling machine rolled thread and the screw plate of cylindrical die roll and rolling compound thread and the processing method of cylindrical die roll.
Utility model patent " compound self-lock screw rod " (patent No. ZL95240473.7) discloses a kind of compound thread, this screw rod is composited by left-handed and two kinds of screw threads of dextrorotation, the screw thread that promptly has two kinds of different rotation directions on same thread segment simultaneously can screw on left-handed and two kinds of nuts of dextrorotation simultaneously.This screw thread has very good self-locking property, can prevent effectively under vibration, variable load and impact condition that especially nut from getting loose.
Compound thread can adopt the method for cutting or grinding to obtain, and can't obtain with common rolled thread instrument.Common rolled thread instrument is single rotation direction, can not time processing go out two kinds of screw threads, and adopts twice method for processing can destroy first kind of screw thread when processing second kind of rotation direction screw thread for the second time.
Adopt cutting or method for grinding machining screw efficient low, be unfavorable for producing in enormous quantities, and the cost height, be unfavorable for applying on a large scale.
The object of the present invention is to provide a kind of threading tool of rolling compound thread.
For realizing this purpose, be provided with the screw thread of two kinds of different rotation directions simultaneously on the surface of the threading tool of rolling compound thread, the thread crest of two kinds of screw threads crosses one another.Use this threading tool can roll out compound thread.
General threading tool can obtain with the method for grinding, also can obtain with the method for roll extrusion, but can't obtain the threading tool of rolling compound thread with the method for regular screw threads grinding machine, reason is that this kind threading tool is to be composited by two kinds of screw threads, the rotation direction difference of two kinds of screw threads, their crest intersects mutually, if can grind away the crest of another kind of screw thread in a kind of screw thread of grinding with the method for general grinding.Also can't process the threading tool of rolling compound thread with twice roll extrusion of roller of regular screw threads, reason is the crest that the roll extrusion of any screw thread will destroy another kind of screw thread.
Another object of the present invention provides a kind of processing method of processing the threading tool of rolling compound thread, just can process the threading tool of rolling compound thread in this way.
The method of processing this threading tool is compound thread roller of first grinding, just can obtain the threading tool of rolling compound thread again with compound thread roller thread-rolling screw instrument stock, after heat treatment can use again.Compound thread on the compound thread roller is made up of the screw thread of two kinds of different rotation directions, and the Bottom of Thread of two kinds of screw threads is intersected mutually.
The invention solves a difficult problem, greatly reduce the production cost of compound thread, for road has been paved in the use of compound thread with rolling depression method processing compound thread.
Fig. 1 is the front view of screw plate.
Fig. 2 is the upward view of screw plate.
Fig. 3 is the front view of cylindrical die roll.
Fig. 4 is the right view of cylindrical die roll.
Fig. 5 is the employed compound thread roller construction of the threading tool schematic diagram of processing rolling compound thread.
Fig. 6 is the processing method schematic diagram of the screw plate of processing rolling compound thread.
Fig. 7 is the processing method schematic diagram of the cylindrical die roll of processing rolling compound thread.
As can be seen from Figure 1, the screw thread on screw plate 3 surfaces is composited by the screw thread of two kinds of different rotation directions, 1 is the crest of screw plate surface right-handed thread, and 2 is the crest of screw plate surface left hand thread, and the crest 1 of right-handed thread and the crest 2 of left hand thread cross one another.
In Fig. 3, cylindrical die roll 1 is the crest of cylindrical die roll surface right-handed thread, and 2 is the crest of cylindrical die roll surface left hand thread, and the crest 1 of right-handed thread and the crest 2 of left hand thread cross one another.
In Fig. 5, at the bottom of the right-handed thread tooth of compound thread 5 and the left hand thread tooth at the bottom of 6 cross one another.
The method of machining screw instrument screw plate as shown in Figure 6, compound thread roller 7 as shown in Figure 5 of first grinding is placed on compound thread roller 7 in two screw plate stocks 8 compacting again, just can obtain the screw plate 3 of rolling compound thread.After Overheating Treatment, can use again.
The method of machining screw instrument cylindrical die roll as shown in Figure 7, compound thread roller 7 as shown in Figure 5 of first grinding is placed on compound thread roller 7 in two cylindrical die roll stocks 9 compacting again, just can obtain the cylindrical die roll 4 of rolling compound thread.After Overheating Treatment, can use again.
The processing method of compound thread roller is the screw thread of a kind of rotation direction of first grinding, again the screw thread of the another kind of rotation direction of grinding on this thread segment.
Left hand thread is revolved ridge apart from different threading tools with the right-handed thread tooth on the roller of institute's grinding apart from about different can processing.
Claims (3)
1, a kind of threading tool of rolling compound thread is characterized in that: the screw thread of two kinds of different rotation directions is arranged on the threading tool surface, and the hand of spiral of two kinds of rotation directions is opposite, and its crest intersects mutually.
2, a kind of processing method of threading tool of rolling compound thread as claimed in claim 1 earlier with method for grinding processing compound thread roller, obtains the threading tool of rolling compound thread again with compound thread roller thread-rolling screw instrument stock.
3, the employed compound thread roller of a kind of processing method of threading tool of rolling compound thread as claimed in claim 2, it is characterized in that: the screw thread on the compound thread roller is a compound thread, described compound thread is made up of the screw thread of two kinds of different rotation directions, and the Bottom of Thread of its two kinds of different rotation directions is intersected mutually.
